It’s probably vortex shedding; curls of higher speed water that oscilate from one side to the other of the rudder.

The likely causes are a little bit of slop between the rudder and the stock or some minor imperfection on the leading edge of the rudder or centreboard.

I think it is great when the boat talks back to you and it generally happens at speed. Just hum along with the boat and enjoy it!
